Stepper motor driver is an actuator that converts electrical pulse into angular displacement. Stepper motor and stepper motor driver constitute a stepper motor drive system. Stepper motor is a kind of special motor used as control. Its rotation is run step by step at a fixed Angle (called step Angle). It is characterized by no accumulation error, so it is widely used in various open-loop control. The operation of the stepper motor must be driven by an electronic device, which is the Chinese stepper motor driver. It converts the pulse signal issued by the control system into the angular displacement of the stepper motor. In other words, each pulse signal sent by the control system will make the stepper motor rotate one step distance Angle through the driver. So the speed of the Chinese stepper motor is proportional to the frequency of the pulse signal. Therefore, the frequency of the stepping pulse signal can be controlled to the precise speed regulation of the motor; The precise positioning of motor can be realized by controlling the number of stepping pulses.
